DETAILED DESCRIPTION OF THE INVENTION

It is noted that, in case no interference is resulted in, the embodiments and features contained therein may be combined with each other. The present invention is described in greater detail in conjunction with the accompanying drawings and embodiments.

Reference is made to FIGS. 1-3. The present invention provides an electronic cigarette which includes a soft hollow pipe-stem 10 composed of a stem portion 11 and a mouthpiece 12. The stem portion 11 is provided with a film 100 onto its external wall. The pipe-stem 10 is made from any one or more of the following soft material: silica gel, rubber, foam or EVA. The film 100 is a paper film or plastic film, and the paper film may be any one or more of the following papers: bond paper, thermal-sensitive paper or coated paper. The plastic film may be any one or more of the following films: PET film, PP film and PVC film.

As a first embodiment and as described above, the film 100 is attached only onto the external wall of the stem portion 11, and the rest exposed portion of the pipe-stem 10 forms the mouthpiece 12. As a second embodiment, the mouthpiece 12 is sleeved with a mouthpiece case 120 made of soft material. Specifically, the mouthpiece case 120 is of a hollow cylinder shape. Alternatively, the mouthpiece case 120 is of a barrel shape, one end of which is opened while the other end is provided with an intake through hole in its bottom wall. Compared with a prior art electronic cigarette of which the external wall of the pipe-stem made from hard material is attached with paper or plastic film, the electronic cigarette of the invention can lead to soft experience of holding a conventional cigar in hand and sucking by mouth, is more mimic, healthier, produces more real user experience, and complies with food standard without causing risk to user health. In addition, compared to a conventional mouthpiece 12 attached with a paper film, the electronic cigarette of the invention is prevented from being soaked by user saliva.

A nozzle case 20 is mounted on a corresponding end of the mouthpiece 12 of the electronic cigarette. The nozzle cas2 20 has an insertion end matched with the pipe-stem 10. A suction hole is defined in the nozzle case 20. In a second embodiment, the intake through hole is coaxial with the suction hole. Here, the nozzle case 20 is made from any one or more of the following material: silica gel, rubber, foam or EVA.

A light permeable cigar cap 30 is installed on a corresponding end of the stem portion 11 of the electronic cigarette. The cigar cap 30 is of a crown shape protruded outwardly and a light source is disposed at an inner side of the cigar cap 30.

The electronic cigarette also includes a cigar liquid cup 40, an atomization component 50 and a battery 60.

In particular, the cigar liquid cup 40 is located inside the pipe-stem 10 and includes a cup body 41 and an atomization cartridge 42. The cup body 41 is coaxial with the pipe-stem 10 and is tightly pressed against an inner wall of the pipe-stem 10. The atomizer cartridge 42 is sealed and secured to one end of the cup body 41. The cup body 41 includes oil retention cotton 410, oil-guiding cotton 411, a first glass fiber tube 412 and a second glass fiber tube 413 all of which are hollow. The oil retention cotton 410 is pressed against the inner wall of the pipe-stem 10 and is coaxial with the pipe-stem 10. The oil-guiding cotton 411 is pressed against an inner wall of the oil retention cotton 410 and placed coaxially with the pipe-stem 10 in a contact region of the atomization component 50. A groove is defined circumferentially at a middle portion of the oil-guiding cotton 411. The first glass fiber tube 412 is a helix formed by enwinding helically a glass fiber wire and is accommodated inside the groove. The second glass fiber tube 413 is pressed against the inner walls of the first glass fiber tube 412 and oil-guiding cotton 411 respectively and is disposed coaxially with the pipe-stem 10. Cigar oil will be accumulated more quickly and holding of the atomization component 50 will be enhanced by means of the above construction.

The atomization component 50 is held along radial direction of the cup body 41 inside the cup body 41. The atomization component 50 includes an oil-guiding member 51 which passes across a corresponding hole of the second glass fiber tube 13 and is pressed against the inner wall of the cup body 412 and an electric heater coil 52 enwound on the oil-guiding member 51. Here, the oil-guiding member 51 is also constructed of glass fiber with good oil absorption effects.

The battery 60 is placed on one end of the pipe-stem 10 corresponding to the stem portion 11. Two electrodes of the battery 60 are coupled with two ends of the electric heater coil 52 respectively through a conductive wire which passes through the atomization cartridge 42 and cup body 41.

The electronic cigarette also includes a holding bracket 70 and a gas sensor 80. Specifically, the holding bracket 70 is provided at one end of the pipe-stem 10 corresponding to the stem portion 11. The gas sensor 80 is secured on the holding bracket 70 and electrically connected to the battery 60. The above structure is stable and reliable.
